    近年来,随着雾霾天气不断增多,受到雾霾天气的影响,户外系统所采集到的图像质量严重下降,导致成像图像不清晰,对比度降低,颜色失真,图像丢失大量细节信息,这样的降质图像给后续的处理带来不便,因此,研究降质图像的复原算法,提高图像质量,具有重要的现实意义。 本文提出一种尺度空间理论,假设图像具有多种尺度表达方式,只要找到合适的模式识别方式,就可以提取出图像的细节跟平滑轮廓信息。本文算法采用光学成像原理来建立数学模型。通过对模型变量进行分析,发现模型中的传输图像函数t,大气光A值的精确估计对图像的复原效果产生较大的影响,因此为了精细化传输图估计,本文基于暗通道理论,采用不同的块操作提取图像的不同暗通...In recent years, the fog and haze weather has been increasinghappened. This phenomenon seriously affects the quality of imagesthat collected by the outdoor system.It causes the image appearsunclear, leads low contrast and color distortion .It makes the image losingrich details.

    核磁共振(NMR)技术作为一种无损的检测手段已被广泛应用于化学、材料、生物、医学等各领域,它在分子水平上对物质结构的解析仍然占据着无可替代的地位。二维(2D)谱的引入又极大地拓展了NMR的应用领域。为了在不均匀场下获取高分辨NMR谱图,研究者又分别从不同方面入手,提出了各种克服不均匀场的方法。如今,复杂有机分子的结构解析相当依赖于质子检测的异核NMR技术。因此,建立快速获取高分辨异核2DNMR谱技术有助于其获得更为广泛的应用。本文的主要研究成果有: 一、首先对空间编码方法基本原理进行了简要介绍。接着对基于空间编码超快速采样技术在不均匀场下获得高分辨2DNMR谱的方法做了全面的综述。介绍了相位...Nuclear Magnetic Resonance (NMR) has been widely used in many fields such as chemistry, material, biology and medicine because of its noninvasive measurement, and still occupies the irreplaceable position on structural analysis at the molecular level.

    我国《侵权责任法》已经明文规定了补充责任,但由于规定得比较宽泛, 缺少相关的司法解释以确定其实施中的细节问题,加上司法实践的多样性与 复杂性,造成审判实践中适用侵权补充责任时的诸多困惑。本文从法理学角 度就理论界对侵权补充责任的研究状况进行疏理和分析,针对近年来审判实 践中出现的第三人侵权情形下安全保障义务人未尽安保义务等案例,从法社 会学的角度进行解析、检视,并着重从法解释学的角度,在侵权补充责任的 承担形态的理解、认定与适用上进行深入的探讨。认为在现有侵权理论框架 内,一般情况下适用无意思联络的数人侵权的方式来确定安全保障义务人的 相应责任,并在某些特殊情况下,适用连带责任...The supplementary liability has been expressly provided in Tort Liability Law of People’s Republic of china.
